Color symbolism in art and anthropology refers to the use of color as a symbol throughout culture. Color psychology refers to investigating the effect of color on human behavior and feeling, distinct from phototherapy (the use of ultraviolet light to treat conditions like psoriasis or infantile jaundice). Color symbolism is a contentious area of study which is dependent upon a large body of anecdotal evidence, but not supported by data from well-designed scientific studies.
Color symbolism and color psychology are culturally constructed linkages that vary with time, place and culture. In fact, one color may perform very different symbolic or psychological functions in the same place. For example red is often used in North America to indicate stop, as with a stop sign, or danger, as with a warning light. At the same time, red symbolizes love, as with Valentine's Day. A person not familiar with the cultural coding of red in North America could, theoretically, confuse the symbolism of red and mistake a red Valentine's Day heart for a warning. Cross-cultural diversity is found in the symbolism of white, which historically has signified purity, virginity or death (as in Herman Melville's Moby Dick). In Western traditions it is the color worn at weddings. During certain periods in history, it was the color worn at funerals in parts of China, Korea, and Japan. White mourning clothes were also worn in medieval Europe.
In Buddhist religious art there is the most famous Stupa of Bodnath showing the color of the Buddha's eyes as light blue. It is not known whether this color is due to symbolism or whether Buddha Shakyamuni is believed to have been blue-eyed.
Common connotations
White
White is the color that represents purity, neutrality, sterility and youth. White is often associated with cleanliness or sterility. White is also associated with neutrality and peace — hence a white flag for surrender or parley. For the same reason it is a neutral color that will continue to be the preferred backdrop on websites and the "color" behind the color. In Western tradition the bride wears white, a custom dating back to Ancient Greece. There, the temple that was dedicated to the goddess Athene was made of white marble. It led to the linking of the color to virginity. In India white is used during death of family members as symbol of sorrow.
White is known for symbolizing light, reverence, purity, truth, snow, peace, innocence, cleanliness, simplicity, security, humility, sterility, winter, coldness, surrender, fearfulness, unimaginative, air, death (in Eastern cultures), life, marriage (in Western cultures), hope, bland, empty (interior) and January (winter).
Black
Black is a multi-dimensional color that can mean classic or new. It has an ominous characteristic symbolizing death. Therefore it is used in Western cultures for funerals. It has an air of intelligence (graduation robes), marked with rebellion (the bad guy), shrouded in mystery (space). It typically symbolizes absence, modernity, power, sophistication, formality, elegance, wealth, mystery, style, evil, death (in Western cultures), fear, emptiness, darkness, seriousness, conventionality, rebellion, anarchism, unity, sorrow, and professionalism,
Gray
Gray, somewhere between white (good) and black (evil), is a blasé color. It can symbolize elegance, humility, respect, reverence, stability, subtlety, wisdom, old age, pessimism, boredom, decay, decrepitude, dullness, pollution, urban sprawl, strong emotions, balance, neutrality, mourning, or formality.
Red
Red strikes a chord with more cultures than many other colors because of its intensity, passion and invocation of an inherent physiological response. Red is the color of celebration and good luck (China), purity and integrity (India), and mourning (South Africa). When used with a wide brush, red typically makes whatever it’s painted on look larger, whether it’s a torso or wingback chair. The color is bold and audacious, so it usually dilutes the colors around it. For this reason it’s used to accent and highlight objects of importance such as the stop light on a traffic signal.
Studies show that red can have a physical effect, including increasing the rate of respiration, raising blood pressure and thus making the heart beat faster. Red is also said to make people hungry (McDonald's, Burgerville, corner cafés). The red ruby is the traditional 40th wedding anniversary gift. Red is also the color of the devil in modern Western culture.
Red typically symbolizes passion, strength, bravery, danger, energy, fire, sex, love, romance, excitement, speed, heat, arrogance, ambition, leadership, courage, masculinity, power, danger, gaudiness, blood, war, anger, revolution, radicalism, Communism, aggression, respect, martyrs, the Holy Spirit, conservatism (US politics), Liberalism (Canadian politics), wealth (China) and marriage (India).
Orange
Orange is energy, enthusiasm, 'get-it-done' attitude, and balance. It typically symbolizes Hinduism, Buddhism (monks wear orange because this vibrant yet soothing color aids in renunciation and spiritual focus), cheer, happiness, energy, balance, heat, fire, enthusiasm, nourishment, flamboyance, playfulness, autumn, desire, Sagittarius (star sign), and September. Orange has less intensity or aggression than red and is calmed by the cheerfulness of yellow. Orange is symbolic of the Royal family of the Netherlands. As such, in the Netherlands, Orange symbolizes royalty, and as William Of Orange was the Calvinist color, orange symbolizes protenstantism, particularly in Ireland (Orange Order).
Yellow
Yellow echoes the dual nature of red. Though yellow evokes feelings of happiness, when we are confronted with too much yellow we become annoyed or angered. Yellow typically symbolizes sunlight, joy, happiness, earth, optimism, intelligence, idealism, wealth (gold), summer, hope, air, liberalism, cowardice, illness (quarantine), fear, hazards, dishonesty, avarice, weakness, greed, decay or aging, femininity, gladness, sociability, friendship, Gemini, Taurus, Leo (golden yellow, star signs), April, September, deceit, hazard signs, death (Middle Ages), mourning (as in Egypt and Frank Herbert's Dune), courage (Japan), royalty (China) and God (gold). Yellow ribbons were worn during times of warfare as a sign of hope as women waited for their men to return.
